Abstract
With the rapid development of wireless communication technology, the wired automatic meter reading system is gradually replaced by the wireless one. In this paper, a new kind of wireless automatic reading system based on digital image processing technology, ZigBee and 3G network is proposed. This design mainly aims to apply in residential buildings or areas, and it uses digital image processing technology template matching method to get the meter data which is fast and really solves compatibility problems in meter reading system. At the end of the paper, securities of transmitting data to remote monitor center by 3G network are discussed. Virtual private network tunneling technology is used in this design which makes data transmission much more reliable and safer than the current meter reading system.
